为什么 flutter 命令“flutter run --release”不起作用？
[英]Why is the flutter command, “flutter run --release” not working?
问题描述
I have built an application using sharedpreferences so i could track who is logged in and logged out the app, but some reason, when i run the command "flutter run --release" it is giving off this error, I know one of them is referring directly to how I am using SharedPreferences, but I don't know how to fix it.
我已经使用 sharedpreferences 构建了一个应用程序，因此我可以跟踪谁登录和注销了该应用程序，但是出于某种原因，当我运行命令“flutter run --release”时，它会发出此错误，我知道其中一个是直接指的是我如何使用 SharedPreferences，但我不知道如何修复它。 Could some please help me?有人可以帮我吗？

First run android folder in your project with android studio and sync it.首先使用 android 工作室在您的项目中运行 android 文件夹并同步它。
And try to change the compileSdkVersion to:
compileSdkVersion 28or uppercompileSdkVersion 28或更高版本
